My gigabyte ga-890gpa-ud3h mb is in a coma after doing the Vista 64bit SP2 upgrade . I just installed both Vista Ultimate 64 and Windows 7 64 on this new build and everything was fine until I fell asleep while it was in stage 3 of the Vista 64 SP2 update around midnight and I woke up three hours later and I guess it was in hibernation/sleep mode. I don't get any display on any of my monitors after doing a cold boot. All of the fans come on etc and the HD light blinks twice every few seconds but get no display. I also pulled the MB battery after unplugging the PSU and put it back in but still no display. If I ever get this going again I will make sure there is no power saving settings because it is not worth the headache.
I have a MSI 5450HD video card with 512mb DDR3 and 1.5TB 7200rpm SATA2 Seagate with Vista 64 and 2TB Seagate 7200rpm SATA3 with Windows 7. BTW the 890GX board has 4290 graphic chip that I had set to ATI Hybrid CrossFireX mode. It ran fine with just Vista and the 1.5TB drive for two weeks and after installing the 2TB with Windows 7 it ran fine with all of the ATI drivers with several reboots for software installs until last night doing the Vista SP2 update while I was sleeping. Windows dual boot startup was set for Vista as the default OS at startup. I checked the 750w PC Power & Cooling PSU with my PSU tester and it tested ok. It has the AMD Phenom™ II X6 1055T CPU and 8GB Corsair CMD8GX3M4A13333C7 1333 DDR3 Dominator RAM for AMD Phenom II. BTW I put in a Linux Live disk at boot up and the DVD drive light shows that it does not load. I tried both DVI ports and the HDMI ports with two different monitors and nothing shows. I also pulled the MSI card and used the motherboard DVI port and still no BIOS screen.
I called Frys.com were I purchased the Gigabyte 890GX MB and AMD X6 1055T CPU combo and they told me I could return it so I did. I will get the ASUS M4A89TD PRO/USB3 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard and AMD Phenom II X6 1090T Black Edition to replace it and use the 5450HD card until the ATI 6000 series cards come out and get the 6970 or whatever it will be called.
Update: Ordered the same gigabyte ga-890gpa-ud3h mb /1055T cpu combo along with zalman cnps9900 led HS/F (to work with my 8GB Corsair Dominator HS/F) and Coolermaster HAF X 942 case that will give me more room to plug in the SATA3 cables compared to my Thermaltake Soprano mid-tower case. It also gives me room for long video cards like the 5970. I ordered the same mb/cpu combo since I have an oem Windows 7 disk activated with that combo and was told it would not activate with a different motherboard. BTW the reason I did not get the Corsair H50 is because with my luck it would leak.
